From Source to Product Signal

Test a Product Idea in Four Steps

IPMA publishes a GeoJSON file of recent Portuguese weather station readings. Start with two features and preserve their timestamps and station IDs; a station reading is not a destination-wide measurement or warning.

1

Check the Setup

  • Python 3.10 or newer
  • An internet connection
  • The requests Python package
2

Access the Data

  1. 1.Read the IPMA API documentation and noncommercial reuse conditions.
  2. 2.Download the current GeoJSON station observations.
  3. 3.Inspect two station readings and their observation times.
Open Official Source

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

url = "https://api.ipma.pt/open-data/observation/meteorology/stations/obs-surface.geojson"
response = requests.get(url, timeout=20)
response.raise_for_status()
for station in response.json()["features"][:2]:
    row = station["properties"]
    print(row.get("idEstacao"), row.get("time"), row.get("temperatura"))

Test a Useful Signal

Show Nearby Station Weather

Present two current IPMA station readings with timestamps.

  1. 01Select stations by their reviewed coordinates and IDs.
  2. 02Display temperature with its station name and observation time.
  3. 03Explain that station conditions can differ from a travel destination.
